Can you explain that graph please? I don't really know what I'm looking at

The green line represents the 100 UMS trend, the blue line represents 90 UMS trend, and the yellow line represents the 80 UMS trend.

You can follow up whichever one you wish and at each vertex, if you look all the way down to the bottom from it, you can see a corresponding value which is a mark out of 75 for the paper that year.

So, if I wanted to know what year and what lowest mark could've gotten me 100 UMS, I can look where the green line is at it's lowest point and follow straight down from the vertex to see the mark, which is 63/75 in Jan 2013

I know this thread is pretty dead atm but does anyone have any predictions on the vector question (if there will be one :smile: ).

As in, do you think it will be one long question worth 10marks or separated into parts like past questions?

Personally, im not sure. I dont think there has been one long vector question before but you never know. Anyone who sat M1 last year will know :frown:

@RDKGames Is there any method of doing top heavy partial fractions without algebraic long division??

Long division is the way to go though. Of course if you don't fancy that, there is also the grid method which might be easier for you if you're familiar with grid multiplication.
any tips on how to come up with the rate of change equations ?

Consider the information you have, construct true equations with the info given, and what think about what kind of rates of change you can get from differentiating your information with respect to something. See how it might help you answer the question.

I don't think you are ready for c4
In the m1 exam last year there was a 10 marker at the end on vectors haha

Can anyone help with 4 b ii?

answer says you get x = 1/3 but I don't know how to get there

I tried to rearrange the "cube root of 1/81" in to "9^-2/3"

but I don't know how to get to x = 1/3?

Edit: Nevermind, solved it

Any predictions for what type of questions are likely to come up?
Anyone got some the hardest vector questions to revise, that's all that's worrying me

Friend and I exchanged these.
Guys I'm really stuck with vectors, I can answer any vector question unless it involves a right angled triangle or a quadrilateral etc. I don't understand how to answer these questions and the mark scheme makes no sense to me. Does anyone have any tips for this?

Draw a sketch. If you're given (or if you prove) that certain vectors are perpendicular, then put that in your sketch. Otherwise you can just draw something.

Is there a particular kind of question that doesn't make sense?

By the way I wouldn't stress about it too much. Just move on if you cannot do the question and come back to it later.
